Abstract (en)
[origin: GB2493411A] Means for determining test particle charge in an electrophoresis system comprises applying one of an electric current or a voltage across an aperture 10 connecting two chambers14, 15, whereby the chambers are at least partially filled with electrolyte and whereby at least one test particle is suspended in the electrolyte of at least one of the chambers; measuring the other of the current or voltage across the aperture; varying a pressure differential between the two chambers; and determining the charge based on the measurements of the electric current or voltage. Direction, velocity, concentration, and distribution of particles may also be determined. Monitoring of blockade events, particle types and driving force balance is also disclosed. An electrophoresis variable pressure system is also disclosed.
